Description of detection logic
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.

IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed: Marked as improvement because we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 5/19/2023 4:22:12 AM, 6/1/2023 4:59:33 PM, 6/7/2023 7:43:49 PM falls between 5/29/2023 5:51:10 AM and 6/7/2023 7:43:49 PM.
IsImprovementStdDev: Marked as improvement because 54.904996216500194 (T) = (0 -338.9235520238095) / Math.Sqrt((95.79322816789413 / (299)) + (8.168562595735118 / (11))) is greater than 1.9676960046166507 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (11) - 2, .975) and 0.1431175658111231 = (395.53098359944073 - 338.9235520238095) / 395.53098359944073 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
